Oh, BTW... Happy Halloween all you freaks!
mnem
I'm trying to work
where and
when Mnem thinks he's living to have All Hallows Eve 9 days early. It can't anywhere that hasn't adopted the Gregorian calendar because the smallest shift, for the earliest adopters, was 10 days. By the time Saudia Arabia decided to finally move into the 16th Century, in 2016, the shift was 13 days. If we assume that he's on Planet Earth
* then, using the Proleptic Gregorian Calendar, he must be in a year \$Y\$ such that \$ Y < 1582 \$ and \$9 = \big \lfloor \frac{Y}{100} \big \rfloor - \big \lfloor {Y\over400} \big \rfloor - 2\$. Solving this is left as an exercise for the student.
So, what planet (and time period) is Mnem on/in? Answers on a Postcard please...
BTW, it's a
blue moon on the 31st (October, 2020, Gregorian Calendar),
*Yes, I know this is, from observation, an
unwarranted assumption, but so are
spherical cows.
